Why should I change the bank reservation number? Why can't my mobile phone receive information?

After changing the reserved mobile phone number, you need to open SMS reminder service.

Counter opening process:

Bring valid identity documents and bank cards to the local bank outlets;

Fill in a business application form, select "SMS Reminder" in the business application column, and attach the commonly used mobile phone number to bind and receive SMS;

Submit bank card, original ID card and business application form;

Enter the mobile phone number and verification code as required;

You can start the SMS reminder service.

Mobile phone turned on:

Call (bank customer service phone) and the bank will manually handle the signing of the mobile messenger;

According to the prompt, provide the bank card number and appropriate identity information, and you can open it.

Note: SMS reminder is a paid service. Generally, it is valid for one year, and the service fee is two yuan per month, which is deducted every month. After one year, you need to apply for the service again before you can continue to use it. If online banking is opened, you can renew the fee in online banking.
